A circular air supply vertical foam generating device

Abstract

The invention discloses an annular air supply vertical foam generating device, which comprises a liquid supply joint, an air supply joint, a foaming cylinder, a foaming net, a foam transport pipeline, an atomizing nozzle and a base, and the base is provided with a liquid supply joint And the air supply joint, the upper end of the base is connected with the lower end of the foaming cylinder, the atomizing nozzle is set on the inner lower part of the foaming cylinder, the atomizing nozzle is connected with the liquid supply joint through the liquid supply pipeline, and the foaming cylinder is set on the upper inside of the foaming cylinder. Foam net, the upper end of the foam cylinder is connected with the foam transport pipeline. The invention overcomes the problems of poor foaming capacity of foam generators, low pressure of foam outlets of traditional foam generators, small spraying force and uneven distribution of foam in the existing underground foam dust-proof technology of coal mines.

Description

technical field [0001] The invention relates to a ring-shaped air-supply vertical foam generating device, which is suitable for dust-reducing operations at dust-producing points such as mining working faces in underground coal mines. Background technique [0002] With the continuous improvement of the degree of mechanized production in coal mines and the increasing intensity of various operations, the traditional methods of mine dust prevention and control can no longer meet the needs of dust prevention in modern production; workers who work in high-density dust environments for a long time are also deeply affected by it Pneumoconiosis is the most serious problem in the coal industry. Correspondingly, the development and innovation of mine dust control technology is imminent. [0003] Foam dust suppression technology utilizes the characteristics of large specific surface area, good coverage, strong adhesion, strong wettability, and low water consumption of foam. It has play...
